The first thing you will have to understand about on demand hot water heaters is there is not tank to have to deal with, and can often be placed in spaces you could never fit a tank heater, no matter how small it was. In order to understand this, here is how on demand hot water heaters work.

Usually you have a heater casing, and depending on the size of the heater, it could fit easily under a kitchen sink. On demand water heaters contain two coils inside a case. The first coil contains water. You cold water line comes on one side, coils around and around in the box, and out the ‘hot’ side. Then another heating coil wraps around the first one. Also, the cold water goes through, it s heated up and comes out the other side as hot water.

One of the biggest benefits of an on demand hot water heater is that there is no large tank storing hot water, which cool down after usage and have to be heated back up. Imagine how much money is wasted every day having to keep fifty gallons of water at 120degrees all the time. With an on demand, the only storage is in the coil, and it’s heated as you need it.

Because you aren’t keeping many gallons of water heated all day long, you save a bunch of money over the initial costs, and are available in both electric and gas models, even ones using LP gas. While electrical units do save you money, the best ones, that heat up water quickly safely as without many problems, gas heater is your best bet, especially if you have gas available in your area.

You should really look around before you buy, because it is a big investment. You are looking to spend up to and over a thousand dollars for a quality unit, any that has any kind of warranty or guarantee. If you see one advertised without a warranty, don’t buy it. Right now, Paloma, Takagi USA, and Bosch seem to be among the top brands.

For sure, just like your normal tank hot water heater, the more demand you put on your unit, the longer it will take to heat the water. You are also going to find that the less distance between the heater and the faucet, or usage the better. Take some time and think about where you will need it the most, or even better yet, install two instead. You can use the larger one close to a well used area, like bathrooms or laundry, and a smaller unit for under the kitchen sink, which can also be used for the dishwasher.

For more energy savings, some units that run on electricity, also run from a solar panel. These can be ideal for lesser used hot water demands, like a pool or hot tub. Solar can run a variety of different things, including your whole house. The nice part about using solar to power an on demand hot water heater, is you can still have a nice hot shower, even in a power outage.

Finding a retailer for an on demand hot water heater isn’t hard, either online or at a local home improvement retailer. While it is a good idea to put these heaters in new construction, you can easily adapt one to fit your own needs.

Many people have really started taking charge of the environment. With the threat of climate change, it is important to many across this country and the world that they do their part to reduce their carbon footprint. Anyone who owns their own home can do this in a really simple way.

Instead of wasting energy with a water heater that has a tank, try an inline hot water heater instead. Because they don’t require a big bulky water holding tank, you can place these units almost anywhere you need them, and often in very small spaces. This eliminates the need to place piping all over your house, and it limits the need for more than one line in most cases.

All you need is the one main water line, and you just split it where you need to put an in line water heater. If you don’t know how one works, it is pretty simple. The unit consists of a holding box, and the only external parts are the in and out ports for the water connections, and either a natural gas line, or an electrical cord. You of course have your thermostat, and settings regulator, but what you don’t have is a big tank of water.

Ironically, on the inside of the container are two coils. A larger one carries water from the input line, the cold water, and hot water comes out the other side. The other coil is the heating coil, which wraps around the water coil, heating it as it passes through. While you may thing this becomes an endless supply of water, it still is going to depend on your demand.

You can simply reduce or eliminate this problem in a couple of ways, and in combination. One of them is to simply install more than one unit, with a larger one close to where there will be a big demand, like a bathroom and laundry area. Another smaller unit could be connected in the kitchen area, to handle the dishwasher and any other kitchen uses. You can also replace many faucets and shower heads with low flow products, and often if you combine these together, you will have an endless supply of fresh hot water.

You can find many quality inline hot water heaters, Bosch, Noritz, and Paloma seem to be in the top five name brands today. Each has its own specialized features, and each range in price. You are going to have a little higher initial investment, but it will well pay for itself and you will see the savings right away in your next power bill.

If you are planning to live off the grid, and want to conserve energy wherever you can, an inline water heater is an ideal choice. Because it is strictly on demand, you won’t be constantly heating up a large quantity of water, no matter how small of a tank model you use. It only comes on when needed, and shuts off automatically when not in use. You can get one that runs on cheaper, more fuel-efficient natural gas, or an electrical model works really well with solar power grids.

For many who are really concerned about conservation usually use an inline hot water heater in conjunction with other energy saving ideas. Low flow showers and faucets, low flow, or even composting toilets. Many common appliances can be run from propane or natural gas, and it doesn’t take very much really to live off self-sustaining power.
